Metaplatforms Inc META is facing a lawsuit alleging that people’s medical information is secretly shared with Facebook when patients access their healthcare providers’ web portals, Bloomberg reports.
According to the report, the pixel tracking tool used by Facebook shares patient communications and other information without their permission.
The lawsuit lists its plaintiff as John Doe and seeks compensatory and punitive damages.

Bloomberg reported that nearly 33 hospitals are using the Facebook tracking tool, which could violate federal health information privacy laws.
According to the lawsuit, there are at least 664 medical providers whose websites have obtained patient data through pixels.
Facebook has been in the firing line over various privacy issues. In February, Texas sued Facebook for its longstanding and discontinued use of facial recognition technology that violated that state’s privacy rules on personally identifiable biometric data.
At the same time, Facebook lost a privacy lawsuit and agreed to pay $90 million to settle the high-profile, long-running privacy dispute.
